The related method includes the following steps: equally divide the original file of size B into k(k+1)/2 blocks, obtaining the first packets; construct a symmetrical k×k system matrix S with these first packets; generate k ID codes, wherein each ID code contains k elements; obtain the coded packet through operations between one column of the system matrix and the ID code; repeat the above steps with (n−k) different columns of the system matrix separately to get the (n−k) coded packets; construct the (n−k)×k check matrix P with the column number g which is the serial number of the ID codes in the coded packet set Pg; store the rows of the system matrix and coded matrix to n nodes, each node stores one row. The present invention also involves a method to repair the failed nodes of the above coding scheme."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Construction of MBR (minimum bandwidth regenerating) codes and a method to repair the storage nodes","description":"This invention gives a coding method of MBR (Minimum Bandwidth Regenerating) codes.
